Guidelines for non-LaTeX Users

If your information doesn't fit the rules (e.g. PowerPoint slides)
or you don't care about the "academic style", format any way you
want to, provided your active area is 165 mm by 239 mm. This should
fit both A4 and Letter paper (210 mm by 279 mm).

If you want to publish your slides, please try to place two to
four slides per page.
